重力トレンド解析法のカリフォルニア州ブーゲー異常への応用

抄録

Boundary detection and texture analysis methods in computer picture-processing techniques can be applied to extracting a fault structure from Bouguer anomaly map . This paper aims at finding effects of San Andreas and Garlock fault systems on the gravity field of California, U. S. A., by using these methods. We conclude that conventionally used two-dimensional running average and second deivatives methods are most effective for extracting fault-related gravity trends.
